Question 1
1 / -0

A speciallised parenchymatous cells, which are closely associated with sieve tube elements is

A
Companion cells

B
Phloem fibres

C
Phloem parenchyma

D
Xylem parenchyma

Solution

The companion cells are specialised parenchymatous cells, which are closely associated with sieve tube elements. The sieve tube elements and companion cells are connected by pit fields present between their common longitudinal walls.

A
Some monocots, such as grass, have hypogeal emergence.

B
Monocots have atactostele type of vascular tissues.

C
Many monocots are herbaceous and do not show secondary growth.

D
Many monocots have leaves with reticulate veins.
